Vessel Registry - Form Fields Logic and Validation
- Troy Bradley
First Registry Request
Vessel Details
Vessel Specs
Field | Validation rules |
|---|---|
Place of Build | Text, no validation |
Year of Build | YYYY |
Hull Identification Number | Alphanumeric, Must be unique |
Vessel Type & Subdescriptor | Subdescriptor options will be based on the Vessel Type selected. See list of potential vessel types and subdescriptors attached to PBI Product Backlog Item 104829: Enter vessel details - Boards (azure.com) |
Construction Type, Construction Material | Drop-down selectors based on matching LOV |
Name of Builder | Text, no validation (for now - we may switch to Stakeholder selection later) |
Propulsion type | Drop-down selector based on matching LOV |
Propulsion power | Number, <10000? (might have to change this later - what’s a reasonable limit on HP?) |
Dimensions & Tonnage
The logic/validation for Dimensions and Tonnage depends on what is selected for Method of Tonnage Measurement
Assigned Formal Tonnage
Only display Length and Gross Tonnage
Field | Validation rules |
|---|---|
Length | Validation - Numbers only; must be <12; support 2 decimal places (e.g. 11.24) |
Gross Tonnage | For Assigned Formal Tonnage, Gross Tonnage field is read-only and the value populated is based on the value provided for Length
|
Simplified Method of Tonnage Measurement
Display Length, Breadth, Depth, dropdown for Gross Tonnage Coefficient, and Gross Tonnage fields
Field | Validation rules |
|---|---|
Length, Breadth, and Depth (L, B, D) | Validation - Numbers only, support 2 decimal places (e.g. 11.24) |
Gross Tonnage Coefficient (GTC) | This is a dropdown with the following values:
|
Gross Tonnage | This is read-only and calculated based on the fields previously entered: L x B x D x GTCValidation - If the calculated value exceeds 15, field is invalid and displays error: “Gross Tonnage cannot exceed 15” |
Certificate of Survey
Logic is simple - User can enter Length, Breadth, Depth, Gross Tonnage. 100 max value for L/B/D, 15 for Gross Tonnage.
Ownership Details
Shares of Ownership
Shares of ownership is a complicated topic, and I encourage you to see the official explanation on the TC website.
For validation the simplest way to think of it is the shares apply to the sequence and not the owners. So the shares for all sequences should add up to 64. The shares are displayed for each owner in a sequence but that amount is “shared” between them.
